Forget the perfect, golf-course green that requires constant watering and harsh chemicals. A healthy Puget Sound lawn is a "meadow green" that thrives on natural methods. Our focus is on building healthy soil, choosing the right grass, and adapting our care to the seasonal cycles of our region.

Spring is all about waking your lawn up from its winter slumber and setting it up for success.

• Cleanup and Prep: Start by raking up any lingering leaves, sticks, and debris that accumulated over the winter. This allows for better airflow and sunlight penetration.
• Mower Maintenance: Sharpen your mower blades. Dull blades tear at the grass, leaving it susceptible to disease.
• Check Your Sprinkler System: Before turning on your system for the season, check for any damage from winter. Adjust sprinkler heads for proper coverage and repair any leaks to conserve water.
• Aerate and Dethatch: Our rainy winters can lead to compacted soil. Aerating in spring or fall helps loosen the soil, allowing water, oxygen, and nutrients to reach the roots. If your lawn feels spongy, it may have a thatch buildup of dead grass and roots. Dethatching removes this layer, which can suffocate the grass.
• Lime Application: The Puget Sound's naturally acidic soil can be a problem for grass. A soil test will tell you for sure, but many lawns benefit from a lime application every few years to balance the pH.
• Fertilize (lightly): Wait until late spring (May) to apply a light, slow-release or organic fertilizer. Fertilizing too early will only encourage a growth spurt that requires more frequent mowing.
• Weed Control: Hand-pulling weeds is a great, low-impact option. Tackle them early before they have a chance to go to seed.
• Overseeding: For thin or bare spots, overseed in late spring. Choose a cool-season grass seed mix, like a fescue or perennial ryegrass blend, specifically designed for our climate.

Our dry summers can be tough on lawns. You have two main options: keep it green or let it go dormant.

• Mowing: Adjust your mowing schedule as growth slows down. Raise your mower height to 2-3 inches. Taller grass shades the soil, conserves moisture, and helps prevent weeds.
• Water Wisely: If you want to keep your lawn green, water deeply but infrequently. Aim for about one inch of water per week, including rainfall. Water in the early morning to minimize evaporation. You can use a tuna can to measure how long your sprinkler needs to run to deliver an inch of water.
• Embrace Dormancy: The most eco-friendly approach is to let your lawn go dormant. It will turn a beautiful golden-brown, but the grass is not dead. It's simply conserving energy. Water it deeply once a month to keep it alive, and it will bounce back as soon as the fall rains return.
• Avoid Fertilizing: Don't fertilize a lawn during the summer heat. This can stress the grass and lead to a host of problems.
• Watch for Pests: Keep an eye out for common lawn pests like European crane flies.

Fall is the absolute best time for a Puget Sound lawn. The cooler temperatures and returning rains are exactly what your grass needs.

• Rake Leaves: Don't let a thick layer of leaves sit on your lawn. Rake them up regularly to prevent the grass from suffocating. You can use a mulching mower to chop them up and return the nutrients to the soil.
• Fertilize: This is the most crucial time to fertilize! Apply a slow-release or organic fertilizer in September or October. This feeds the roots as they grow, storing nutrients for a strong start next spring.
• Overseeding: Fall is the ideal time to overseed. The moist, cool conditions are perfect for new seeds to germinate and establish strong roots before winter.
• Aerate: If you didn't aerate in the spring, do it now. It's especially beneficial after a dry summer to help the soil absorb the returning rain.
• Sprinkler Winterization (Blow Out): Before the first hard freeze, it is critical to have your sprinkler system winterized. This involves using an air compressor to "blow out" all the water from the pipes, heads, and valves. This simple step prevents pipes from freezing and cracking, saving you from costly repairs in the spring.
• Continue Mowing: Keep mowing as needed until the grass stops growing, usually when temperatures consistently drop below 50 degrees.
• Winterize Equipment: Clean and sharpen your mower blades before putting your equipment away for the winter.

Your lawn is now dormant and requires very little care.

• Stay Off the Grass: Avoid walking on waterlogged or frozen grass. This can damage the crowns of the grass plants.
• Plan Ahead: This is a great time to plan for the next year. Consider any new projects, research new plants, or check your equipment.

By following this checklist, you can enjoy a healthy, resilient, and beautiful lawn that works in harmony with the unique climate of the Puget Sound region.
